Habitat and Ecology
Terrestrial|Freshwater (=Inland waters)
-
This species is an ovoviviparous semi-aquatic snake that inhabits human-affected environments including rice paddy fields (Xiang 1995, Zhao et al. 1999). It is also found in grasslands, swamps, along the banks of rivers and stagnant pieces of water. It mainly feeds on frogs, fish, lizards, and, more rarely, on rodents (Szczerbak 2003).

-
This species is locally threatened by extensive agriculture, the disappearance of grassland and swamp areas, and the use of various pesticides. However, due to the wide distribution of this species, these cannot be considered major threats at present. The decline of amphibian populations may also be affecting this species (P. David pers. comm.).
